An ethanolic extract of B. monniera exhibited marked anti-inflammatory activity against carrageenan-induced paw oedema in mice and rats (Channa et al 2005). The effect was mediated via PGE2 inhibition and found to be comparable to aspirin. Bacopa has also exhibited anti-inflammatory activity comparable to indomethacin without causing an associated gastric irritation (Jain et al 1994). Several constituents are thought to be responsible for the anti-inflammatory action, chiefly the triterpene, betulinic acid but also saponins and flavonoids.
